Parser still recognizes --help option even when i set the parser setting "AutoHelp" to false #596
Comments
It looks like I'm indirectly responsible for causing this behavior to happen, actually. In gsscoder/commandline#225, I asked for "Option 'help' is unknown" to NOT show up when running a verb-based command like "my-cmd verb arg --help". The solution that was implemented at the time was a band-aid that filters out UnknownOptionError if (and only if) the unknown option in question is the "--help" option. The real solution is to not use a bandaid, but to handle the |
I've created #600 as a design document to discuss the right solution, BTW. |

When using a parser with the
AutoHelp
setting set tofalse
i would expect the parser to not recognize the--help
option unless i have it explicitly declared as part of my options class. If i have no such declaration, i would expect the parser to treat--help
as an unknown option/error. Unfortunately, this is not the case. The parser still recognizes this option, even whenAutoHelp
is set to false :(The documentation comment for
AutoHelp
(also shown by Intellisense) seems to support my expectations:But that does not seem to be what that setting actually does...
Thus my question: What is the actual purpose and supposed effect of setting
AutoHelp
for the parser tofalse
? And how would i make--help
not an option?For example, if i use the unknown option
--foo
, theHelpText.AutoBuild
method is able to generate a text containing:I want to get the same result when calling my program with the (unknown) option
--help
:Unfortunately, the parser or
HelpText.AutoBuild
method seem to refuse to treat--help
as an unknown option (both parser settingsAutoHelp
andIgnoreUnknownArguments
are set tofalse
):-(
